The pawn on e5 will require protection, and there's also a plan for White with f3-f4 at some point, opening the diagonal for the dark-squared bishop.
13... f6g4 Abdusattorov tries to gain some activity, but this probably worsens his position. 13...b6 or 13...Bd7 leads to a normal position with a slight but comfortable advantage for White. 14. e5g3  14... e6e5  15. f2f3  15... g4f6
